- They are small, beetle-like insects that belong to two species
- Paederus eximius and Paederus sabaeus.
- They are orange and black in colour, and thrive in areas with high rainfall.
- Like most insects, the beetles are attracted by bright light.
- Effect on Human
- Usually ,it attacks pests that consume crops and are beneficial for humans but at times, they come in contact with humans directly and cause harm.
- These flies do not bite, but if disturbed while sitting on anyone’s skin, they release a potent acidic substance that causes burns.
- This substance is called pederin, and can cause irritation if it comes in contact with the skin, leading to lesions or unusual marks or colouring on the skin.
